Microcomputer Associates was founded by Manny Lemas and Ray Holt. It produced the low cost Jolt Microcomputer, released in 1975. It was later acquired by Synertek, a second source manufacturer of the 6502, and renamed Synertek Systems. It then created the SYM-1, a 6502-based single board microcomputer and successor to the KIM-1. Holt designed the JOLT microcomputer. In 1978 the company offered a number of processor and peripheral modules.
